Frequently Asked Questions
Planning a loft conversion? You’re not alone.
We understand that starting a home project can raise a lot of questions — from planning permission and timescales to cost and disruption. This page is here to give you clear, honest answers to the most common questions we hear from homeowners across Greater Glasgow.
If there’s anything else you’d like to know, just get in touch — we’re always happy to help.
How much will a loft conversion cost?
The cost of a loft conversion in Greater Glasgow typically ranges from £40,000 to £200,000+, depending on the type of conversion, the size of the space, and the finishes you choose.
- A Velux (rooflight) conversion is usually the most cost-effective option.
- Dormer and hip-to-gable conversions tend to sit in the mid-range.
- A roof lift or mansard conversion will be more structurally involved and therefore more expensive.
At GLA Lofts, we provide a clear quote after your consultation, with no hidden extras — so you know exactly what you’re investing in.
Which loft conversion should I choose?
The right conversion depends on your home, your goals, and your budget. Here’s a quick guide:
- Velux Conversion – Best for lofts with good existing head height; minimal structural change.
- Dormer Conversion – Ideal for adding full-height usable space and often allows for en-suites.
- Hip-to-Gable Conversion – Perfect for homes with a sloping side roof (e.g. semis or bungalows).
- Mansard Conversion – Maximises space in terraced homes; usually requires planning permission.
- Roof Lift or Pitch Increase – Needed when your current loft doesn’t have enough height.
During your consultation, we’ll assess your space and recommend the most practical and cost-effective option for your home.
Can a loft conversion be classed as a bedroom?
Yes — as long as the space meets building regulations, a loft conversion can legally be considered a bedroom. This includes:
- Adequate ceiling height (usually at least 2m above the stairs)
- Proper access via a permanent staircase
- Fire safety measures (such as smoke alarms and fire doors)
- Suitable insulation, ventilation, and structural stability
We take care of all the regulatory aspects, so you can be confident your new room is safe, compliant, and fully usable.
Are loft conversions worth the money?
Absolutely. A well-designed loft conversion can add up to 20% to the value of your home, according to UK property experts. More importantly, it gives you space to grow without the hassle or cost of moving.
Whether you need an extra bedroom, a home office, or a new family bathroom, a loft conversion can transform how you live — making your home work better for years to come.
How long does it take to build a loft conversion?
The typical build time for a loft conversion is between 6 to 12 weeks, depending on the type and complexity of the project:
- Velux (rooflight) conversions – usually 4–6 weeks
- Rear dormers or hip-to-gable conversions – around 8–10 weeks
- Roof lifts or full mansards – up to 12 weeks or more
This timeline includes structural work, joinery, insulation, plastering, and first-fix electrics and plumbing — but not necessarily finishing like decoration or flooring. At GLA Lofts, we provide a realistic, tailored timeline at the quoting stage, and we’re known for working efficiently while maintaining quality.
How do we choose the right contractor for our loft conversion?
Choosing the right contractor is one of the most important steps in a successful loft project. Here’s what to look for:
- Experience – Look for a company that specialises in loft conversions and has completed similar projects in your area.
- Team continuity – A long-standing in-house team ensures consistent workmanship (GLA Lofts’ core team has worked together for over 10 years).
- Accreditations – Choose a contractor registered with bodies like the Federation of Master Builders (FMB), which offers added peace of mind and insurance-backed warranties.
- Transparency – Clear pricing, schedules, and communication from day one are essential.
- References and reviews – Ask to see case studies and speak to past clients if possible.
